How to get rid of bathroom sink odor


Odor, foul, stinky, smelly odor coming from your bathroom sink is not normal.  Whenever you notice this type of odor from the overflow pipe of your sink, you know that there is a problem.

Something to suspect immediately is there could be a layer of gunk or bacteria colony growing in the pipe far beyond what you can see.

So what should you do to get rid of the bathroom sink odor?  Read these quick tips on how to solve the problem really fast.

Things You Need

Before you begin trying to clean the source of the bathroom sink odor you have to make sure that it is the actual source of the problem.

For example, if the smell happens when you turn on the faucet, try to catch the water in a bowl and take a whiff to confirm the smell of the water.

If the water has a foul odor, the problem may have something to do with the faucet or the aerator cap, which can also gather gunk fairly quick depending on the quality of your water.

You can also look into the barrel of the faucet and make sure it is free from dirt.  If your faucet is fairly old and the smell still exists, consider replacing the faucet with a newer and more efficient one.

Usually if you smell something like rotten eggs, it is a sign of sulfur presence.  You need to verify the quality of the water from the supply provider.  As far as cleaning is concerned, there are a few things you need to prepare:

  • Half a cup of baking soda;
  • Quarter of a cup of table salt;
  • Cup of warm distilled white vinegar;
  • Turkey baster;
  • Oxygen bleach; and
  • Clean cloth.

Cleaning Procedure

cleaningYou do not have to buy commercially available cleaning solutions to try to get rid of bathroom sink odors.  Check the detail information at You can use simple household items to effectively clean out suspected gunk from the overflow pipe, faucet, or other possible sources.  Here is what you have to do:

  • Combine the baking soda with the table salt to create a mixture with a natural scouring action. Pour the mixture down the bathroom sink.
  • Pour in the cup of warm distilled white vinegar down the sink. Allow the mixture to foam by letting it sit for at least 15 minutes.  Take note if the mixture comes through the overflow pipe because of the foaming action down the drain.  If there is none you may need to rely on the oxygen bleach.
  • Use hot water to flush the drain for about 30 seconds. The turkey baster should be filled with hot water and squirt it vigorously into the overflow pipe so that the portion of the drain system can be rinsed out.
  • Verify if there is still foul odor coming from the bathroom sink. If there is still a trace of foul odor, this means that the foaming action of the mixture is not strong enough to remove the smell.  Open a source of ventilation like a window and put oxygen bleach enough to fill the turkey baster.
  • The tip of the turkey baster should be inserted into the overflow pipe so that you can squirt enough amounts of oxygen bleach that will reach deep enough into the pipe to remove any remaining source of foul odor. This process should be repeated about 3 to 4 times with the oxygen bleach allowed to sit for about 20 minutes or more.
  • Thoroughly rinsing the pipe would require hot water being squirted into the pipe using the turkey baster. Take the clean cloth and dip it in the distilled white vinegar and use it to wipe the insides of the overflow pipe.  This should kill any living bacteria in the mouth of the opening.  The vinegar should evaporate on its own.

This is the simplest way that you can get rid of bathroom sink odors.  Just remember that oxygen bleach can be a bit toxic so always use protective gloves.
